UPS / Battery Backup Questions

post #1 of 8
Thread Starter 
hey everyone,

I am interested in getting some UPS systems for my PC and NAS server to avoid any data loss and shorts once I get my new build going and I have a few questions / concerns.

First of all here is the main rig I want to have on a UPS backup

1x i7 970 oced to ~4.2ghz
3x GTX 680 4gb probably OCed
12gb ram ddr3 2000mhz at 1.65v
2x SSD
+watercooling
all on a 1200w PSU

in addition I plan to have a monitor on the UPS backup but I am also considering having it on a second backup, this will most likely be the case since as the wattage increases so does the price of these UPS systems.

So far I have already purchased the following UPS system:

http://www.amazon.com/gp/product/B000OFXKFI/ref=oh_details_o01_s00_i00

here are my main questions:

Would this system alone be enough to sustain my system if I were to get 2: 1 for my PC alone and one for my 300w NAS Server, monitor, switch, router, modem etc..?

if my PC were to say draw +1000w from the 800w UPS while without power would something bad happen to the UPS or would it simply run out of power faster?

what would happen if even without running on battery backup, my PC drew more than the 800W from the UPS even with the UPS plugged into the wall?

I am entertaining getting a 1200w UPS but these are so cheap and I would only need a few minutes of battery backup so if I could run my system off of 2 of these even at full load that would be pretty nice and I could save out on $80+ on the 2nd UPS I plan on getting.

any help would be greatly appreciated, thanks!

Generally you shouldn't push a UPS around 60% over its rated output in VA. On to your questions:

1. Assuming you don't pull 1000W from it, it will keep the system running long enough for it to shut down safely.
2. Depending on how it is built, the UPS would likely beep to tell you that it is severely overloaded and will eventually shutdown to protect itself.
3. There is no way an 800W UPS will be able to supply 1000W whether on AC or DC.

If you are to be drawing 1000W, you'd need roughly 2000VA which would be about 1200W when you account for the fact that the wattage rating is roughly 60% of the VA rating. This is a de-facto industry standard.

Be aware of what you plug into the battery side. I know this sounds simple but I managed to leave my monitor not plugged into a battery ac plug so when I had my UPS a long time ago and the power did go out my computer was still on, but I couldnt see to shut it down safely :-| .

thanks for the input!

I already ordered the UPS I posted in the OP and that should be enough to run:

1x 8 Port Switch Switch
1x Modem
1x Router
1x 300w NAS Server
2x External HDD
and hopefully 1x Monitor
and possibly 1x RAID Enclosure w/ 4x 2-3TB HDDs

long enough to shut everything down although I plan on having it so it will auto shutdown when the power goes out

I was looking at this UPS for my main system: http://www.amazon.com/Maruson-PRO-2000ALCD-2000VA-1200W-System/dp/B003V4AK3E/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=161V44FFKRSB5&coliid=I1P21H0LIBEOWE how well do you think that would work for the gaming rig I posted in the OP, even it was at full load folding, bitcoin mining etc?

Ideally I would like to put a monitor on it so I can put my dedicated firewall box on the other UPS to properly shut that down but if need be I can work out another solution for that or just say screw it

800W should be plenty for those devices - but that depends on the monitor.

I couldn't see anywhere that the 2000VA unit you linked was line-interactive. This one here is: http://www.amazon.com/Ultra-ULT33046-2000-1200-Backup/dp/B000GC98H8/ref=cm_cr_pr_product_top
The reason why line interactive UPS' are an advantage is because it can automatically variate the voltage using an autotransformer. This is good for undervoltage brownouts and overvoltage surges as generally the autotransformer can adjust to a range of about 90V - 140V, and engage the inverter to use reserve battery power to compensate if brownout goes below this range. If a surge goes above the range of voltage adjustable by the autotransformer, the UPS will redirect the current directly to the ground.

If you can find anywhere that the PRO-2000ALCD is line-interactive, then go for that one for sure smile.gif

my monitor is theAsus VG236H 3d monitor. I will actually have 3 in surround but there is only need to have 1 plugged into a battery plug, I'm sure the others should be safe enough simply behind a surge protector. according to reviews the monitor draws a maimum of 50w so that shouldn't be too much for that UPS and I could debateably even put it on the 1200w I plan on getting without interfering with my 800w UPS in order to provide a little more headroom for additional minutes of battery backup for other components.

thanks for suggesting that Ultra UPS. I was looking at that one too but the reviews were kind of sketchy but not terrible. As long as it will keep my rig safe I could really care less about the little bit of an extra price. I can always shop around and try to find a better deal anyways but what is 300 dollars if it keeps a 3000+ dollar rig safe and sound during power issues.

Over all would you say having a UPS is a little frivilous or a necessary component to safeguard your rig from unforseen power related issues?

thanks for the help!

edit:

I found this really cheap "line interactive" UPS, any suggestions?

Yes one of them will be fine on the 1200W smile.gif
Its hard for me to recommend a UPS - I'm in Australia and I use Eaton and SOCOMEC but the one I linked looked pretty good smile.gif

But you're damn right - I spent a lot on good power protection as it is definitely worth it and hardly frivolous at all.
Wow funny that the one you linked is Eaton! They generally make great units
